C211B-00-IGNITION RUN/START INPUT

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Continuous.

- Set Condition:
No ignition voltage sensed at the module.





1. DTC IS ACTIVE

NOTE: If multiple DTCs are present, inspect the wiring and harness connector at the EHPS Pump.

1. Turn ignition on.
2. With the scan tool, record and erase DTCs.
3. With the scan tool, read the DTCs in the EHPS Module.

Is the DTC status Active?

Yes

- Go To 2

No

- Test complete. The condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

2. (F944) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT SHORTED TO GROUND




1. Turn ignition off to the lock position.
2. Remove Fuse 39 from Front Power Distribution Center.
3. Disconnect the EHPS Module C1 harness connector.
4. Measure the resistance between ground and the (F944) Fused Ignition Switch Output (Run-Start) circuit in the EHPS Module C1 harness connector.

Is the resistance below 10k Ohms?

Yes

- Repair the (F944) Fused Ignition Switch Output (Run-Start) circuit for a short to ground.
- Perform the EHPS Verification Test. EHPS Verification Test.

No

- Go To 3

3. (F944) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN OR HIGH RESISTANCE
1. Measure the resistance of the (F944) Fused Ignition Switch Output (Run-Start) circuit between the Front Power Distribution Center Fuse 39 (output side) and the EHPS Module C1 harness connector.

Is the resistance above 5.0 Ohms?

Yes

- Repair the (F944) Fused Ignition Switch Output (Run-Start) circuit for an open or high resistance.
- Perform the EHPS Verification Test. EHPS Verification Test.

No

- Replace and program the Electro-Hydraulic Power Steering (EHPS) Pump. Power Steering Pump - Removal.
- Perform the EHPS Verification Test. EHPS Verification Test.
